[MMTK] Nose-Hoover chain thermostat

[Yoonjung Huh]

Hi,
I am wondering if anyone has included Nose-Hoover chain thermostat in  
MMTK.  I have been trying to do that, first by creating a new  
thermostat that does exactly the same as the existing  
NoseThermostat.  I have been modifying MMTK/Environment.py and Src/ 
MMTK_dynamics.c to make a copy of NoseThermostat, but I am having  
some troubles...  Any suggestions will be really appreciated!!
Thank you very much,
Yoonie
